IMPROVED RUBBER-COLLAR.

The Schedule referred to in these Letters Patent and paxb of the same To all whom 'it 'may concern: l l

Be it known that I, SEWALL LEACH, vof Penobscot, in the county of '.Hancock, and State of Maine, have invented a new and useful Improvement in Rudder- Collars; and I do hereby declare that the following, taken in connection with thedrawings which accompany and form part of this specication, is a descrip'- ti`on of` my invention sucient to enable those skilled in the art to which it appertains to practice it.

This invention relates to a new and useful' improvement in the collar which encircles the rudder-head at the upper surface 'of the vessels deck; and

The invention consists in a metallic collar vertically divided inl two equal parts, one'part of which is firmly secured tothe deck, while the other half is arranged Vto be adjusted relative to the'xed half', so as to pre` vent the usual lateral motion of the rudder-head, and

the consequentponnding and thumping in roughv weather. In the accompanying drawings- Figure 1 is a top or plan view, and Figure 2 is a athwart-ship vertical section. Similar lettersv4 of reference indicate corresponding parts in the several figures. In the drawings- A representsthe deck, and` B the rudder-head;

.while a is the tiller, and b, a thin metallic casing upon the rudder-head. i

C represents the half of'` the collar which is secured to the deck by-screws, as shown, andV y C is the adjustable half which is pivoted upon screw e, as shown.

f is a screw-bolt, which passes through lugs formed upon C and O respectively, as shown, and upon which is iitted a screw-nut. By actuating the bolt f, any desired degree of' pressure may be exerted uponrudder B, by the collar C and C. v

An elastic packing may be combined with the collar, if in any case it may be found necessary.

By the use of this collar the 'rudder is kept noiseless, land having no lateral motion, much of the usual friction and wear is avoided, while the danger of the rudder being unshipped in heavy 'seas is greatly lessened if not entirely avoided.

" Having thus described my invention, V

What I claim as new, and desire to securev by Letters Patent, is-

A rudder-collar, adjustable substantially as described and shown.
